For this season, the Bundesliga is no longer boring with several teams starting to show their good performances at the beginning of this season where Bayern Munich, which used to dominate the Bundesliga, has started to decline in consistency. Although that is not the end of Bayern Munich at this point because Bayern Munich still has time to perform well and occupy the top of the Bundesliga standings. But Bayern Munich actually have to fight first to win some games and also beat opponents who are already in the top position at this time.
It would be much more interesting to see not a "competitive" Bundesliga (due to the fact that Bayern fell into a losing streak) but the success of the German teams in the Champions League. At the moment, nothing has changed - Leipzig is in last place in the group with zero points, Bayer shares 2-3 place with Atlético (both teams are 3 points behind Brugge lol), Eintracht shares 2-3 place with Tottenham (3 points behind Sporting), Borussia in a clear second place (3 points behind City). It is very likely that again, apart from Bayern, no one will reach the playoffs or will be destroyed there in the first round.
The Bundesliga is obviously a lot more interesting this season. There is no longer a huge difference between Bayern Munich and its closest rivals in terms of points. The Bayern Munich team is currently ranked 5th in the table and despite the fact that only seven matches have been played so far, I am genuinely starting to believe that the Bundesliga will likely be decided by a different team this time around.
There is no guarantee that Union Berlin will win the Bundesliga, but I think as long as Bayern Munich is not going to be the league winner, the competition is going to be interesting in this league in the future.
